Former deputy, police reserve charged with assaulting 4-year-old in Sheridan

Michael Shane Abo, 34, an inactive reserve police officer for the city of Yamhill and a former Yamhill County Sheriff's deputy, was arrested Saturday morning by McMinnville police for allegedly physically abusing his girlfriend's 4-year-old son.

The boy is listed in critical condition at Oregon Health & Science University in Portland, according to police.

Abo is charged with two counts each of first-degree assault and first-degree criminal mischief. The assault charge is a Class A felony and Measure 11 offense, punishable on conviction by a mandatory minimum prison sentence. The criminal mistreatment charge is a Class C felony.

He is lodged in the Washington County Jail in Hillsboro on $1 million bail. Given Abo's local law enforcement connections, he was moved to Washington County from the local facility. He tentatively will be arraigned at 1:20 p.m. Monday in Yamhill County Circuit Court.
